Simple rule of thumb. Anything that looks too good to be true almost invariably is just that.
One of my mantras nowadays.
I had a similar situation to OP. Got chatting to a woman on Illicit Encounters, without even exchanging pic passwords she wanted to move to Kik (red flag 1). On Kik she sent some absolutely hot photos, nothing nude but gorgeous woman (red flag 2). Within a few exchanges she asks me to share a fantasy (red flag 3)... Anyway, I was chatting to a few other women at the same time so I just humoured her, had some exchanges here and there, pretty consistent, but I always kept her at arms length, remained non committal and tried not to waste too much time on her. I get pics of her with her family, pics of her laughing at her desk at home, a silly video of her singing, complaining about her controlling husband etc etc... My gut tells me something is off, it just doesn't feel right somehow.
One day I tell her I've been working in London, "Why didn't you tell me! We could have had lunch".. I was like, "I came in for a work meeting and went home, and anyway you said it was difficult for you to arrange meetings due to your controlling husband". Fucking weird man.
So, to cut a long story short, one day, out of the blue, she ended up messaging saying "I need your help..." I was like, "Yeah?". And she claimed her kids needed money for some video game subscription. I just replied, "I knew this was a scam. Bye bye." and deleted her.
This was like three weeks after we first made contact, talk about longing it out! The poor blokes who must get duped and rinsed by these people.
